. To all whom it mag concern." i i Be it known that I, MIorrAEL J.WILLIAMS, a citizen of the United States, residing at Buffalo, county ofErie,and State of New York, have'invented a new and usefulImprovement-in Hairpins, of which the fol-- lowing is'a specification. ii

This invention relates to hair pins.

' More particularly the invention relatesto the type of pins such as isshown in the patent granted to me--No. 1226836; This type of pinembodies prongs which are turnable or flexible, relatively to eachother, to define loops in which strands of the hair are confined inplace the pin being prevented from falling out of the hair or disengagedtherefrom.

Some of the objects of the present invention are: to produce a hair pinwhich embodies sinuous prongs which normally cross each other, theprongs being; capable of flexing action so that upon the insertion ofthe pin in the hair and by imparting thereto a slight twist the prongswill reverse themselves and will in their changed. relation define aloop for the hair which has passed between the prongsthe prongsimpinging against each other by virtue of the inherent flexibility ofthe material from which the pin is made; to produce a hair pin of thecharacter set forth from a piece of flexible wire which is covered witha'fiexible cover-. ing such as celluloid. With these and other objectsin view the invention resides in the particular formation and functionsof the parts hereinafter more fully described and illustrated in theaccompanying drawing, in which:

Figure 1 is a side elevation of the hair pin of the present invention,and in which the prongs of the pin are shown in their normal relativepositions.

Figure 2 is another elevation of the pin with the prongs as shown inFigure 1.

Figure 3 is a view similar to the view shown in Figure lbut showing theprongs reversed and as they would he were the pin applied.

Figure 4 is a view similar to Figure 2 with the prongs as shown in.Figure 3.

conjunction with eyeglasses, because a suitchain may be properlyconnected to the .p1n.

several views of the drawing fordetails, it will he manifest that, thepin of the present invention shown in Figures 1 to' 5 inclusive, isbentand formed from a single element to define a bight 10 from which extendprongs 11 and 12-. The prongs 11 and 12 are substantially identical information as regards their sinuosity. Each prong is bent or convexedinwardly just below the bight 10, bent. outwardly and slightlyrebentinwardly and then outwardly thus providing a relatively longcurved part. 13 which merges with a part 14 which is 'bent or curved andthen rebent as at 15 to extend into a substantially straight part 16having Referring now more particularly to the a pointed end 17. Theprongs are so formed a on the bight 10 and have such relation to eachother that the parts 15 of the prongs cross each other twice. It may nowbe well to mention thatthe element from which the pin is formedpossesses the desired degree of flexibility; that the prongs in theirnormal relation as shown in Figures 1 and 2 have a tendency to keepslightly spaced so that strands of the hair may readily pass be tweenthem in the application of the pin to use. The pin is pushed into thehair the proper distance when it is twisted. The twisting, and inasmuchas the prongs are in engagement with the hair, causes the prongs to bereversed, that is to say, the prong 11 instead of lying or beingdisposed on one side of the other prong 12, disposed on the oppositeside of the said prong 12. lnder this relation of the prongs, they havea tendency to impinge against each other due chiefly to the inherentflexibility of the element from which the pin is made, and duepartly tothe formation of the pin. Under the reversed arrangement of the prongs aloop 18is formed as shown in Figure 3 and in such loop the strands ofthe hair are confined. When it is desired to remove the pin it is onlynecessary to first exert a twisting action at the bight 10 which againreverses the relation of the prongs to their normal condition thusallowing the pin to be readily withdrawn.

The element from which the pin is formed like other pins of thischaracter is covered or coated. Pins now on the market are enamelled orjapanned, While this may be i form of clone with the pin of the presentinvention it is one of the objects to cover the material 7 such as asteel wire with a flexible covering Such as celluloid 19, s shown inFigure 5 As shown in'Figure 6 the pin has a bight 21 which isfOrmedby-crossing the prongs. The bight 21 is therefore in the a circleto which a chain orthe like may be connected for the connection of thepin 20 to eye-glasses, exception of the bight 21 willbe made identicallyto the pin of the preferred form.

What is claimed is: r I 1 1.' Ahair pin bent and formed from an elementpossessing flexiblen'ess to provide prongs which cross each other" twicenormally slightly spaced throughout the major POItlOllS'Of their lengthandwhich are capable of being brought-to a relation so-as to define aloop and inwhich relationthe prongs impinge each other. v

2. A hair pin bent and formed from an element possessing 'flexiblenessto provide sinuous prongs which cross. each other twice normallyslightly spaced throughout the The pin 20 Lwith the major portions oftheir lengths, and which are capable of being brought to a relation soas to define aloop, and in which relation the prongs impinge each other,the said "prongs each having a comparatively straight partbelow thelowest point at which they cross each other.

3. A hair jpin bent and formed from a composite element possessingflexibleness, to provide sinuous prongs l'LZIVIDg'CUTVQCl parts whichintersect each other twice in the normal relation of the prongs butspaced to- 7 permit the passage of strands of hair therebetween,the-twisting ofthe pin when engaged in the hair causing a reversedrelation of the said prongs inwhichthe said curved parts impinge eachother due to the fiexibleness of the element and the formation of thepin.
